soorr, or FORT WORTH, TEXAS AIR COMPRESSOR 1928. Serial My invention relates to compressors and more particularly to double compressors and means to conserve the power usually lost in the operation of compressors; and the object is to provide simple power jacks which may be used as single power acks or double power I plained. Other objects and advantages will 7 be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application. p

Fig. 11 is an end elevation of the same. Fig. 12 is a plan view of the same. Similar characters of-reference are .used to indicate the same parts throughout the several views.

The air compressorshown in Figs. 1 to 3 inclusive has two walking beams 1 and 2 and stationary fulcrums 3 and 4., Normally the walking beams 1, and 2 are i'ulcrumed inthe supports 3 and l-respectively. Means is'pro-. vided for actuating the walking-beams 1 and 2. A combined fly-whe'el and power wheel 1 is provided with a shaft 5 which is jour- No. 202,067, filed June 28, 1927. This application fil ed October 23,

naled in bearing means 6 provided for the shaft, 5. The wheel 1 is driven by a motor 7 which is providedv with a drive pulley 8 I .11. Two bars 12are attachedrigidly to the beam 1- and the link bar 11 is caught in between the ends of the bars 12 and pivotally connected to the bars 12, the object being to pivot the link bar 11 on the walking beam 1. The walking beam 2 is connectedtothe power wheel 4 in a similar manner. Bars 12 are-rigid with the walking beam ,2. A .link bar'13 is pivotally connectedto the bars 12 and the link bar 13 is pivotally connected to a crank 14. The beams 1 and 2 may be strengthened by truss rods 15 which are attached to the bars 12 and to collars 16 which are rigidly connected to the walking beams.

, The walking beams 1 and 2, Figs. 1 and 10, are

provided with weights 21. Pipes 22 and 23 and 2 1 connect the cylinders 17 with a storage tank 25,

In operation, the motor 7 drives the gearing which actuates the walking beams 1 and 2. On the down stroke of a walking beam, the air is compressed in a cylinder 17 The motor is driving the wheel 4. On the upstroke of the same walking beam, there will be no loss of power because the weight 21 will balance all the weight of the mechanism on the other side of the fulcrum 3. The walking beam 2 operates in precisely the same manner and In all the forms of this invention, there is a power wheel 4:. In Figs. 7 to 12 inclusive, a fiy wheel 27 co-operates with the power wheel 4. In Figs. 4: to 6 inclusive, pump 28 takes the place of the weights 21 of the other formsof invention. The compression in the pump cylinders 28 takes the place of the weight 21 which is approximately one thou sand pounds. The compression in pump 28 resists the load just as the weight 21 resists the load. The pumps 28 are mounted on stands or supports 29 and the pistons for the.

pumps 28 are actuated by the bars 30 which are pivotally connected to the walking beams 1 and 2 and pivotally connected to vertical bars 31 which engage cross bars 32 which actuate the piston rods of the pistons. The link bars 31 and the cross bar 32 (operating) in slot 29 of support 29 constitute a yoke.

Figs. 7 to 9 inclusive show means forincreasing the power of the walking beams 1 and 2. The devicesshown in these Views show a slight variation from the devices shown in Figs. tto 6 inclusive. The tank 25 is shown in a different position. The flywheel 27 is in the same position, but the band wheel 4 is located in a different position but is driven in the same manner. 8 A cog wheel 36 is rigid with the shaft of wheel 4' and this cog wheel 36 meshes with and drives a pinion 10 which is rigid with the shaft 39 of flywheel 2'? and drives this shaft.v The fly-wheel 27 in this variation is a driven fly-wheel.

used for temporarily shifting the stationary fulcrum of the walking beam to a movable fulcrum and means are provided for increasing the power of the walking beam on the piston of the compressing cylinder, such means being the weight 21 and the variations in the levers 33 and car 36 and the fulcrum 35 and shaft 39, and the pump 28 and its mechanism.

Inthe forms of compressor shown in Figs. 4 to 9 inclusive, compressed air is taken from the lower parts of the cylinders 17 and compressed air is taken from the upper parts of cylinders 28 by means of pipes 22, 23, and 2 1 Considering Figs. 4' and 6, the piston in cylinder 1'? on the lower side of Fig. 6 is compressing downwardly and the piston in cylin der 28 on the lower side of Fi 6 is compressing upwardly. .At the same time the piston in cylinder 17 on the upperside of Fig. 6 is going upwardly for a charge and that in cylinder 28 on the upperside'is going downwardly for a charge. On the upper side of the Fig. 6, the cylinders operate in the same manner but alternately relative to the cylinders on the lower side of Fig. 6.
